#42Did they not just launch yesterday and they are already half way there? Am I wrong?
They are right now only 44000km not 170000km, it's ai hallucinated slop (unless... NASA app is also ai slop...)
Re: Show HN: Made a little Artemis II tracker
#43This has always been a peeve of mine, but the lack of scale diagrams in coverage of this is maddening. We know what the Earth and the Moon look like, there is no need to make them 20 times bigger. Surely the point of these diagrams is to show the unbelievable scale of the journey. I'm yet to see one this news cycle, from NASA or anyone else
Here's the one I use: https://issinfo.net/artemis

#44I recommend https://issinfo.net/artemis over the surge of vibe coded Artemis II trackers. Seen two others so far and they've all had major inaccuracies either regarding trajectory, current distance, or current mission state. One even said the remaining mission time was over 400 days. They all obviously used Claude Code.
Absolutely ... https://issinfo.net/artemis is the one I use.
Great sense of scale, lovely to see the Moon apparently a long way from the "intercept" point, and it seems "accurate enough".

#45To me, what's super interesting about this is the fact that my brain instantly recognized it's AI coded (not sure why, it might be the spacing, the font, the text glow, etc.).
What's even more interesting is that data is completely off compared to official sources, and the author doesn't even have the decency and self-reflection of checking if their slop is at all accurate before posting it to the HN front page.
Vibe coders, like the eggman himself, are philosophical zombies.

#46Why is a horizontal line constantly falling down? It’s so distracting, I feel like I can focus on the content

I think it's because the UI sucks, like really bad. Why is there a CRT-type line in the background going down constantly. The mission timeline has weird colors that make no sense. Some graphs don't even fit their parent element. And so on.
I don't care if its vibe-coded but if you looked at this and thought "yeah that looks good", it only shows how bad you are at UI.
These types of interfaces are cool if you're like 12
Re: Show HN: Made a little Artemis II tracker
#48It says the distance from Earth right now is 154,000km, but the other trackers, including NASA, say 30,000km (numbers rounded). The velocity is different as well, 7km/s vs NASA's 4km/s.
I am fetching space weather from NOAA SWPC.
Trajectory, distance, speed, and comms delay are computed from NASA’s published Artemis II mission plan parameters, not pulled live from NASA telemetry.
Also, the current discrepancy is likely caused by the orbital phase and reference model being used. Right now the tracker shows about 192,000 km, while NASA’s AROW shows about 80,000 miles, which is roughly 129,000 km. So yes, that is off by around 60,000 km.
difference can happen because the spacecraft is in a elliptical orbit and different trackers may be using different assumptions, interpolation methods, .. or reference points for the trajectory.

#49I don’t think the current position of Orion is accurate. It shows them about halfway to the moon, but they’re just leaving Earth orbit right now.
Hey, I've responded before, I need to update the visualization: Iam fetching space weather from NOAA SWPC.
